SPECIFICATION forming part of Letters Patent No. 377,688, dated 'February 7, 1888.`

Application med october 1o, resi.

To @ZZ whom it may concern.-

Be itknown thatvI, CHARLES M. PowERs, a citizen of the United States, residing at Dubois, in the county of Clearfield and State of Pennsylvania, have invented certain new and useful Improvements in Tool-Handles; vand I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and gures' of reference marked thereon,which form a part of this specification.

This invention relates to tool-handles, and aims to produce a handle which will hold different sizes of tools, and which can readily be detached from one tool and quickly applied to another, and when so applied cannot become detached accidentally.

The improvement4 consists in the clamping devices for securing the tool in the handle and the provisions for supporting the clamping devices, and the means for securing the parts of the handle together.

-The improvements further consist in the peculiar construction and combination of the parts, which will be more fully hereinafter set forth and claimed, and shown in the accompanying drawings, in which- Figure l is a longitudinal sectional view of the handle, showing the handle in position; Fig. 2, an edge View of the toolclamping deviceand the tool removed from the handle; Fig. 3, a side View of the handle andtool,show ing the end of the handle detached; Fig. 4, an end view-of the handle; and Fig. 5, a detail the tool-clamping device, showing the parts detached and in their relative position.

The tool-handle is made in two parts, A and A', which are fitted together by a scarf-joint. (Shown most clearly in Fig. 1.) The end of the part A is recessed and the approximate end of the part A has acorresponding projection, a, which, iitting'in the recessed end ofthe part A, prevents the parts A and A fromlatpart A has a bore, C, and diametrically-opposite longitudinal grooves d, which receive a portion of' the tang e ofthe tool E and the ends The ySerial No.251.98. (No model.)

' the catches G are pivoted. The part A hasa corresponding bore, C', which is enlarged at the outer end of the handle, and receives thepreviously mentioned, have the catches G pivoted between them.

The catches G aresufcientlylong to incline inward and have their ends meet, or nearly meet, so as to fit in the notches e in the edges of the tang and grip it, and they are held in engagement with the tang by the spring J, which surrounds the plates F and bears on the catches between their 'pivotal supportsz and their inner ends. To release the catches from the tang of the tool, they have extensions g, which afford a purchase for the fingers. Now by pressing upon the extensions g the inner ends of the catches will be forced outward and permit the disengagement of the'tool from the clamping devices. v

Toadjust a tool, theparts A and A are separated by unscrewing theend A and clamping device removed from the part A. The tang is pressed between the catches until they enter the notches in the edges of the tang. Now the shank with the clamping device attached is inserted in the part Afronnv the vferruled end m until the threaded stem I protrudes from the opposite end, as shown in Fig. 3. Now the end Af is screwed on the said stem I until the parts A and A are heldtogether with sufticient tension. To disengage the tool, the reverse of thisoperation is performed, the end A is unscrewed, the tool and the v clamping device removed from the part A, and the ends g of the catches G pressed together, so as to disengage the catches, as hereinbefore more particularly described.

Having thus described my invention,what I claim, and desire to secure by Letters Patent, v

part recessed and the approximate lend of the other-part correspondingly raised and each.

1. The herein-described tool-handle, coml posed of the two parts, having the end of oney roo part longitudinally bored,the one havinglongi tudinal grooves diametrically opposite to each other, the nut located within the bore of the other part, the threaded stem, the plates having cross-heads, the catches pivoted between the ends of the cross-heads of said plates, the extensions projecting from the catches, and the spring for pressing the ends of the catches together, substantially as and for the purpose described.

2. The combination, with the tool-handle havingabore, of the catches pivotally supported between their ends on diametrically-opposite sides of the bore, and having their inner ends adapted to grip the tang of atool, the coilspring J, constructed and arranged to exert a pressure on said catches to one side of their pivotal supports for pressing the ends of the y catches together, and the extensions g, substantially as and for the purpose described.

3. The combination, with the tool-handle having a bore and longitudinal grooves diametrically opposite to each other, of the plates F, for supporting the toolclamping devices located in the bore, each plate having a crosshead and the ends ofthe cross-heads working in the said longitudinal grooves, the catches pivoted between the ends of the cross-heads to grip the sides of a tool-tang between their inner ends, and having extensions which work in the said longitudinal grooves, and the spring for advancing the inner ends of the catches together, substantially as specified.

4. The combination, with the tool-handle made of two parts, A and A', the part A having a bore and longitudinal grooves d, thepart A having a bore, G', which is enlarged at its outer en d, and the :nut fitted in the enlargement of bore C', of the threaded stern adapted to screw into said nut, the plates F, having cross-heads f secured to the stem, the catches having extensions pivoted between the ends of the cross-heads, andthe spring J, surrounding the plates and bearing against the catches between their inner ends and their pivotal supports, substantially as and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES M. POWERS.
